Looking good! I have been interested in upgrading to LEDs for heat issue reasons, as my 600w MH/HPS bulbs are simply too hot for my 5x5 tent during summer months. I've found what seems to be a very good LED, especially for the price (includes true UV, 12 band full spectrum unlike most others claim). Anyways, it's the Higrow optical lens series 1000w, consuming around 400w of actual power. $229 with free shipping on Amazon. Just throwing this LED out there for you to see how efficient it seems to be. Most likely will need 2 in my space, but that's not an issue with less heat output. What's your price tag on the Mars? Heat issues or anything? Does it include true UV? I know UV is beneficial for trichome development/higher potency.

Please STOP throwing misinformation about.
This is precisely the reason people get so confused when looking at led fixtures to replace your HID rigs.
The diodes used in the fixture you listed are NOT as efficient at converting watts of electricity into photons of light as an HPS lamp so more of each watt consumed is wasted as heat.
Better components are where leds can have a substantial increase in efficiency-like almost double the amount of light for each watt of power.

If everyone growing had $1000+ plus to drop on "the best LEDs", then I assume they would. I can assure you that the HIGROW would be perfect for lower budget growers for personal use. The Mars hydro the OP uses seems to be doing well, and I'm pretty positive the HIGROW can match/surpass that light in effectiveness. A lot of LEDs twice the price of the HIGROW have the same spectrums and UV as it has, so that makes me confident in its abilities, especially after seeing video results of the grows under it. I'm not trying to steer anyone in a certain direction in lighting, just simply suggesting looking into the light if you want full spectrum AND UV, something similar LEDs in the price range can't accomplish.

So they reckon 400w of crappy diodes replaces 1000w ROFL... Beware of Chinese companies they love making false claims lol!!!
Might as well stick with 600W HPS or go 315W Cmh route way better than that crappy fixture;
You do not need a $1000 to buy the best LED tech $185 gets you 2 x QB Rspec boards + Heatsink add in a driver and wiring and you have just got yourself a top-end fixture for $235 which will cream the pants off that HIGROW fixture, and damn near keep up with a 600W HPS

The claims aren't false if they can be backed up. My post was meant to be an easy solution if you didn't want to fuck around, but was ready to grow. HEAT is my issue, hence the reason why I want LEDs without having to modify/break the bank. I live on a limited income with many different ailments, so everything isn't practical for every person. For my grows, I do what's easiest and most convenient for me, while maintaining cost effective and beneficial requirements when necessary. I'm not a salesman, not a drug dealer, just someone who likes to grow my own smoke. If I were looking to fry the fuck out of my plants during the summer months, I would get the 1000w HPS. I live off of $700 a month disability, so I can't get too crazy with electrical costs.So they reckon 400w of crappy diodes replaces 1000w ROFL...

The point you seem to fail to realize is that a HPS fixture of the same wattage will produce more light and less heat...

Maybe you fail to realize that exhaust fans run electricity, air conditioners run electricity. I'm attempting to cut down on these things. I'm thinking long term, as in less electrical costs due to the lights being less wattage overall, with a full spectrum. The LED I posted is more than adequate enough for full term growth. Also, I do know that more lights = more heat, even if they run cooler. I'm not trying to match the claims of a 1000w comparison, just trying to match the success of my 600w HPS, while producing less heat than the exhaust, light itself, ballast and so on. If I were trying to match a 1000w HPS, then of course my area would be hot as hell, attempting to match the footprint of the HPS with 3 or 4 of those LEDs would put off an absurd amount of heat. I'm wanting 2 in my 5x5 tent, with my double hose portable ac cooling outside the tent with the vents facing an exhaust hole, forcing colder air between the lights and plants. Tent sealed off, except for the exit hole opposite of the side I'm pushing air into. The air will travel out the top exhaust hole in the tent. With a 600w HPS when it's 90+ outside during the day, my tent stayed 80+ during lights off, and around 85 with lights on at night time. This was the coolest my room has been, but the temps did spike at times. Cooling LEDs seem much easier, but I'm not here to argue about me wanting to be cost effective, I'm here to explain what I found at a reasonable price, and why it would work for me.

Cost me 260 total. Heat is low overall and spread out across the board well, but the fixture does get hot, drawing about 300-310 watts. For the small space its more efficient than the 600W HPS that was in there previously (and 300W less heat). Not sure about the UV, not too concerned about it though.

What do you mean??? I see absolutely no evidence of them backing up their claim, that there crappy 400w fixture is the equivalent to 1000 hps all I see is some slick marketing and someone who looks like they have fallen for it. I think that piece of junk would have trouble keeping up with a 600w HPS
I hear you, but I cannot in good conscience agree with your statement as that light is a load of crap and I wouldn't want you to get ripped off. Besides what's 10mins out of your life to wire up a QB kit which is far superior and will yield you more than that falsely advertised Chinese piece of junk; surely you'd prefer something that yielded more and produced a higher quality crop right?

Aren’t QB lights made in China?

Video results hu? Were they a comparison?

I never said anything about a comparison between the 1000w vs the $229 LED. The videos I have seen were similar to what my set up is with a 600w. I can yield 1-2 pounds by leaving the HPS on 24 hours, rotating plants every 12 hours. I have vegging plants in the tent under that 24 hours of light the whole time. 8 3 gal smart pots, 4 in the tent at a time, other 4 in a dark area. This is by far the best way I've found to have weed consistently, while minimizing what I have to do. It's basically 1 light with three grows going, but it gets hot in the summer here, so an LED or 2 would be more practical for me. The results were there in the videos, the results measured by gram per watt. An average HPS grow will be around 0.5 g per watt, but an LED converts each watt into maximizing spectrum/par, ect. This let's the LED focus the watts strictly for the focus of the plants, so an LED can yield around 1 g per watt, twice as effective, while consuming half the power. I never once stated it would replace ANY 1000 W HID, but it will match a 600W if used correctly.

So, you can come to this thread and bash me for showing an affordable LED that WILL work just fine, but don't have any suggestions towards the OP about upgrading? Pretty sure Mars is made in China as well. I was just saying how good his plants were looking under the Mars, which I KNOW isn't top of the line. Neither one of these LEDs are top of the line, but will give good results when given an actual opportunity to. 5 years ago, these LEDs would be considered a revolution, cost so much more than they do now. Forget I mentioned anything about this shitty light until I have a grow going with results of performance.THAT SHIT IS TRASH!!!

Dude even that Mars light is alot better. Made in China doesn't matter but the diodes do. I'm really sorry you wasted a chunk of your check on that light but it won't produce as much as you want it to. Don't expect more than .5g per watt and that's off actual power draw not claims. I know your going to come in here posting pics of ok looking veg plants saying it works great when the flowers are dry you will be disappointed
